Two default views? How to get back to one

You might come across a scenario where you see that Microsoft CRM lists two different views as the "default" for an entity (as shown in the screenshot below):

Obviously this is not the intended behavior as only one view should be listed the default. Changing the default view and re-publishing the entity with the web interface does not appear to correct this issue. While we're not 100% what causes this scenario, we have figured out a method to fix it.

First you need to export the customizations.xml file for the entity. Then open the customizations file and search for the duplicated defaulted view and change the

<isdefault name="Yes">1</isdefault>

To

<isdefault name="No">0</isdefault>

Note that when you find the view "name" in the customizations.xml file, it is actually at the bottom of the node. This means you will need to scroll up in the file to find the <isdefault> node.

Save, import, publish and you should be all set again.
